The open source community should feel a little safer from software patent attacks, writes InfoWorld's Simon Phipps. "The Open Invention Network, a consortium of Linux contributors formed as a self-defense against software patents, has extended the definition of Linux so that a whopping 700 new software packages are covered, including many developer favorites. Just one hitch: The new definition also includes carve-outs that put all Linux developers on notice that Phillips and Sony reserve the right to sue over virtualization, search, user interfaces, and more."
